Market abuse

Finansinspektionen (FI) monitors that the market complies with the Market Abuse Regulation (MAR).

According to MAR, exchanges, trading venues and persons professionally executing transactions are obligated to report to FI any observed trade orders or transactions that can be assumed to be related to insider trading, market manipulation or unlawful disclosure of insider information, or attempts at such. These market participants are also responsible for reporting suspicious trade orders and transactions to FI.

If FI makes the assessment that an infringement has occurred, FI may intervene, for example, by issuing an administrative fine. If FI makes the assessment that a crime has occurred, FI will turn over the matter to the prosecutors at the Swedish Economic Crime Authority. FI may also, on its own initiative start investigations into trading on the securities market.


All preliminary investigations in criminal cases are subject to confidentiality in order to avoid compromising the investigation, for example by someone trying to hide or destroy evidence. Provisions regarding confidentiality of preliminary investigations into criminal cases are set out in Chapter 18 of the Public Access to Information and Secrecy Act.
